• Advanced knowledge of Java 21 and modern JVM-based backend development • Spring Boot 3.x ecosystem, including Spring Web (REST APIs), Spring Security (OAuth2 Resource Server), Spring Data JPA / Hibernate, and Spring Cache (Redis) • Designing and operating RESTful APIs and event-driven architectures • Apache Kafka (producers, consumers, consumer groups, retry strategies, DLQ patterns) • Redis for caching and ephemeral data • Docker and Kubernetes (Deployments, Services, Ingress, ConfigMaps, Secrets, probes, rollout/rollback strategies) • Cloud-native environments on Google Cloud Platform (GCP), including GKE • CI/CD pipelines and GitOps workflows, including Tekton pipelines and ArgoCD • Observability practices, including structured logging, metrics, and monitoring • Automated testing using JUnit 5, Mockito, and Testcontainers • gRPC service communication • WebSockets for event streaming • OAuth2 / OIDC authentication flows and JWT validation • OPA (Open Policy Agent) for policy-based authorization • Identity broker integrations and token validation flows • Google Cloud services, including Cloud Logging, Cloud Monitoring, and GCS • Helm or Kustomize for Kubernetes manifest templating • MapStruct and Lombok in Spring-based applications • JVM performance tuning basics • Cloud networking fundamentals (VPC, subnets, load balancers) • mTLS implementations • Pub/Sub messaging patterns • Advanced Kafka patterns (schema evolution, idempotent producers) • Kubernetes networking concepts (CNI, Network Policies) • Sidecar security patterns (OPA / Identity Broker) • Contract testing • Performance testing tools (JMeter, Gatling) • Strong communicator, able to articulate complex ideas clearly across disciplines and time zones. • Proactive and accountable, with ownership of technical delivery end-to-end. • Comfortable mentoring others and driving technical alignment within a cross-functional team. • Resilient under ambiguity, with a mindset for continuous learning and improvement. • Collaborative, inclusive, and customer-focused. • Exposure to frontend architecture (e.g., Angular, RxJS) for cross-functional alignment. • Experience with performance tuning, cost optimisation, or SLA/SLO definition. • Familiarity with architecture runway planning or domain-driven design (DDD). • Hands-on with observability stacks (Prometheus, Grafana, OpenTelemetry).
Responsibilities
• Solution & Vision: Craft and maintain C4 diagrams, technical roadmaps, and Architecture Decision Records (ADRs) that balance functional requirements, performance budgets, security, and cost models. • Technical Leadership: Drive decision‑making through whiteboard sessions and proofs‑of‑concept; champion design patterns (hexagonal, event‑driven, reactive) and modern non‑functional requirement trade‑offs (for example, CAP theorem). • Backlog & Planning: Partner with Product Owners to decompose epics into tech user stories, help the team with the estimation, and risk‑flag stories so they’re technically “Ready” and aligned with the architecture runway. • Mentorship & Knowledge Transfer: Coach and mentor mid and senior‑level engineers in architecture principles, design patterns, and code quality to accelerate our team’s growth toward senior and architecture roles. • Code & Quality Gates: Define coding standards; review pull requests for readability and test coverage; embed SpotBugs and SonarQube; collaborate with QA to automate smoke, performance, and security tests. • CI/CD & Platform Modernization: Own and optimize pipelines (Tekton/Jenkins to ArgoCD); assess and drive remediation of technical debt; plan platform modernization (monolith to microservices); adopt emerging technologies where appropriate. • Observability & Resilience: Define dashboards and SLIs; implement structured logging and distributed tracing; drive operational excellence through metrics, monitoring, and resilience validation practices.
